President Barack Obama told his staff that he’s “really good at killing people,” according to a new book “Double Down” set to hit shelves Tuesday.

Authors Mark Halperin and John Heilemann allege that Barack Obama has said some questionable things in private. The two state that during a discussion about drone strikes with his aides, Obama told them he’s “really good at killing people.

The Nobel Peace Prize winning president has been slammed for his use of drone’s to carry out political attacks, and this certainly won’t help his cause. It also won’t be going away. Barack nominated Jeh Johnson, one of the drone strike’s biggest defenders for secretary of the Department of Homeland Security.

Obama has been skewered by critics on both the political left and right for his frequent use of unmanned aerial vehicles to carry out attacks against alleged terrorists.
